Cite a doctor in-text for APA style by using the author's last name and the date of publication in parentheses.
Cite a doctor in the reference list by using the last name and first initials but not the title. For example: Jones, A. L. This method is true for any resource in APA where the author is a doctor.
Use the doctor's title in the text of the paper if you feel it is essential to include it. APA does not include a doctor's title in the works cited page or the in-text citation but you can state that you are referencing a doctor's work in the paper's text. For example: Dr. Jones published a study on viruses.
